Booking window

The period during which an award flight can be booked, from the opening of reservations until the applicable cutoff before departure.

Illustrative example

Illustrative example: a traveler planning Chicago (ORD) to Tokyo (HND) checks too early, before the program opens bookings for that date. The flight is outside the booking window; this alone does not show that award seats have sold out.
